You can now do this with the stem splitter tool inside Logic Pro 11.
If you go to file -> Project Settings -> Smart Tempo & set [Project tempo mode] to [Adapt project tempo] when pulling in a recording, then set it to [Keep Project Tempo] any regions subsequently added can be in sync with the imported track.
Now it's possible to split the track into stems, you can mute the drums and add drummer regions, and the new drums will automagically be in time.
I did this yesterday with a track I originally recorded in the late 80s using my trusty fostex x-15 portastudio. The drums were from a Yamaha RX11 drum machine and I always thought they could be improved upon. Using the technique I outlined above, I muted the drums stem, and set up some drummer regions with Logic's simmons kit with a bit of gated reverb. After some more remixing (Logic's octaver pedal on the bass etc) and mastering I think the track now sounds very much improved, but still of the period.
